The route an airplane flies along is called an air traffic line, or route for short. The aircraft route not only determines the specific direction, start and end points, and stopping points of the aircraft's flight, but also stipulates the width and flight height of the route according to the needs of air traffic control to maintain air traffic order and ensure flight safety. The route network composed of airports, aircraft and other elements is a prerequisite for airline flight plans and crew arrangements. It has an important impact on the airline's operating efficiency and customer service quality. It is an important factor for the airline's survival and the basis of development. At the same time, route accessibility represents the activity of urban business travel activities to a certain extent, which is in turn linked to the city’s primacy and economic potential.

  Based on the origin and destination of aircraft flights, routes can be divided into three categories: international routes, domestic routes and regional routes.

• International routes refer to routes connecting two or more countries;
• Domestic routes refer to routes within a country, which can be divided into three categories: trunk routes, branch routes and local routes;
• Regional routes refer to routes within a country that connect ordinary areas and special areas, such as routes between mainland China and Hong Kong, Macao and Taiwan.

  CnOpenData data team has compiled flight information from domestic cities, providing routes, departure places, destinations, flight numbers, departure time, arrival time, departure airport, arrival airport and other fields to assist related research.
